For today’s applications, one of the challenging aspects is to optimally utilize the linux task scheduler. This is because the scheduler is expected to provide optimal performance across a wide range of architectures, ranging from embedded devices to massive multi core NUMA systems. This also means a complex load balancing algorithm with a lot of heuristics. We talk about how an application developer can utilize these heurisitcs and improve performance of their application. At the conclusion of this talk, you should be in a position to identify if the scheduler is buggy and a fix is needed in the kernel or whether something else needs to be tweaked.
